Vectors in 3D don't adjust ArrowTip correctly

For example vector = Vector((2,2,2)), the arrow tip will only align to the x-y plane which is really frustrating. I think it has to do with the way the tip is repositioned (rotation).

Strangely enough when you initially position the vector in the X-Y plane, then rotate it around a circle, it appears to maintain the correct positioning? I'd imagine something like that would be an adequate fix to it, as right now it's a simple degree rotation which doesn't encapsulate the third dimension.
